Leading Technology
Diffusion- absorption summarizes the cooling process, which is also called absorption.

Main features of diffusion- absorption
- Compact and elegant structure, occupies little space, various models, leading technology
- Flat style design, integrated handle
- With no compressor, Freon free, pollution free
- Noise free, long service life
- No vibration, good preservation effect
- Auto defrost
- Total enclosed cooling system, no need to charge refrigerant again
- Imported material, unique technique, safe and durable
- Inclination, inversion and unstable voltage has no influence on the normal running of the refrigerator
- How absorption cooling works?
  
  This system uses three operating fluid as the component: Ammonia – water –Helium, Ammonia as refrigerant, water as absorbent, Helium as diffusant. The refrigeration core is mainly composed of generator, condenser and evaporator. Under the environment of low press in the evaporator, liquid ammonia evaporates into helium and mixes with gas helium together. In the absorber, gas ammonia is released from the mixture and is absorbed by water to be strong ammonia solution. Then, in the heater it is heated and the ammonia evaporates from the solution. Passing through the condenser, steam ammonia is cooled down to ammonia. After that, ammonia water reenters the evaporator. As a result of physical changes, endothermic-exothermic reaction is brought into being time and time again.
- European absorption technology
  
  Thanks to great contribution of engineers from Europe, and their numerous years of experience, Dellcool developed absorption technology with Helium, new corrosion inhibitor ensuring the product safety efficiency and reliability. Dellcool is the only manufacturer in China who can offer quality absorption refrigerators from 15 liter to 300 liter.
- Fuzzy logic temperature control
  
  In comparison with electro-mechanical thermostat, Dellcool can also provide PLD fuzzy logic temperature control option. It has these advantages: Precise, Automatic defrosts, low fluctuation of temperature. This technology provides longer enduring cooling, accurate temperature for proper nutrition and all food value. Energy consumption is very low as well.
- Automatic minibar, Internet of things
  
  As a combination of Dellcool’s cooling expertise and partners’ intelligence, Dellcool’ s computerized minibar is the new generation of automatic minibar that offers accurate billing system. The significant saving in labor costs makes it the first choice of hotel chains.
